摘　　要：试验以250枚31周龄的伊莎褐合格种蛋为研究对象,设置不同的贮存时间(1周,2周,3周,4周),贮存条件为14%,相对湿度为60%,对其孵化率和蛋内营养物质进行检测分析。结果表明:(1)随着贮存时间的延长,种蛋的孵化率显著下降,其在1周内的孵化率与超始孵化率差异不显著(P>O.05),第2周显著低于第1周(P<O.05),第3周显著低于第2周(P<O.05),第4周降低至20%(P<O.05)。(2)随着贮存时间延长,水分含量、蛋壳/全蛋均随之显著下降(P<O.05),蛋白/全蛋,哈氏单位也有下降但差异不显著(P>O.05),蛋黄/全蛋显著升高(P<O.05),鸡蛋蛋白质含量、蛋壳钙含量差异不显著(P>O.05),蛋黄内脂肪含量先上升后下降,磷脂含量随着贮存时间延长逐渐升高。In order to study relationship of the qualities and hatchability of hatching eggs of different storage periods,we set,in this experiment,four different storage periods(1 week,2 weeks,3 weeks,4 weeks) at 14 ℃,and at 60% of relative humidity for 250 qualified 31-week-old eggs,and obtained the following results:(1) with the prolongation of storage time,the hatchability of the eggs decreased significantly.There was no significant difference between the hatchability of the initial period and the first week(P>0.05).The hatchability of the first week eggs was 80.75%,that of the second week ones was 70.35%,that of the third week ones was 51.25%,and that of the fourth week ones was 21.25%.(2) During storage,the content of moisture,ratio of shell/egg,albumen/egg,Haugh Unit value,yolk/egg decreased significantly(P<0.05),the differences in the calcium content in the egg shell and the protein content were not significant(P>0.05),the yolk fat content increased after the first drop,and the phospholipid content increased as the storage time extended.The content of egg yolk fat increased but subsequently decreased,and the content of phospholipid increased as the storage time got longer.
